DNA replication occurs in of cells.
A: Nucleus : eukaryotic
B: Nucleus : prokaryotic
C: Nucleus : plant and animals only
D: Cytoplasm : eukaryotic

The option (A) is correct. Replication in the prokaryotic organism takes place in the cytoplasm in contrast to the eukaryotic replication that is confined to the nucleus.  

Explanation:

Replication is the initiation of biological inheritance and is characterized by the creation of two newly synthesized strands. The process is initiated by the addition of primer to the respective template strand with the help of the enzyme primase. A specific defined sequence known as the "origin of replication" is targeted and recognized by the initiator proteins marking the initiation process followed by elongation and termination. A replication fork is also created that eventually forks the leading and the lagging strand. The creation of a replication fork for the synthesis of the leading and the lagging strand is the characteristic feature of replication. The process is carried out by the disintegration of the double-stranded DNA molecule that serves as the template. The disruption of the hydrogen bond is done by the helicase enzyme that is associated with the unpackaging of the genome of an organism.
